This is a phenomenon any scientist who has been practicing for any length of time is likely to have encountered. I can't even recall all the statements from ignorance (not pejorative--they simply weren't educated on the subject matter) people have made to me about various physics and engineering topics that have been settled for decades in knowledgeable circles.

> settled for decades in knowledgeable circles.

Which also describes phrenology, the static universe, and phlogiston theory.

This is an extremely smug and tone-deaf take on the deterioration of trust in public health institutions and messaging. They reference covid in their abstract, so it's fair game to discuss here: where was the scientific objective-truth-machine when the Noble Lies[0] where being told? It was silent and complicit. The general public is not as knowledgeable as experts, but they can sense when they're being lied to, or w…

> I do think GM crops are bad, though, because they are associated with strain patenting and seedless plants; because they contaminate neighbouring organic plots with non-organic DNA; because they are often sold in conjunction with herbicides; and frankly, because I hate the way their lobbyists act on our legislators.

Are most of these an intrinsic problem with "GM crops" in general or with "most GM crops as delivered now"?

Those two are sort of inseperable. We don't optimize for some theoretical patent free GM crop world.

That is another phrasing issue, because it would be reasonable to take the question as a practical one meant to refer to the things that actually exist, but it would also be reasonable to take it as a theoretical one like you're suggesting.

You've heard of "Blue skies research", this is what I call "The sky is blue research". Working very hard to show something that is pretty much self evident. I'd love it if we could learn how to change people's minds. Calling people stupid hasn't worked.

Actually, I think it's important to not just hand-wave but understand the overall psychology of it.

I've known very informed cranks (some of whom are on the edge of being useful contributors to the field by proposing alternative mechanisms and rigorous tests) and poorly informed cranks.

But it is an interesting, if not entirely unexpected finding, that people with anti-consensus views have much lower scores of knowledge in related but not directly connected scientific fields, but are willing to bet higher amounts on their test scores.
